About this 1ct lab-grown round diamond

This 1ct lab-grown round sits in the classic one-carat band, graded I colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG817652945 or 817652945. Listed at 16 retailers as of October 25, 2026, with prices from £283 to £809, a £526 spread on the same certified stone. MOH London lists it at £809. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
